| 摘 要： | 本研究结果表明，施药后３０天，灭幼脲三号１２５ｍｇ／Ｌ、灭扫利１００ｍｇ／Ｌ、水胺硫磷４００ｍｇ／Ｌ对金纹细蛾的防治效果分别为９９．１％、４１．０％、５２．１％，灭幼脲三号常用剂量对金纹细蛾跳小蜂成虫和蛹茧，以及异色瓢虫２龄纪虫无直接毒性，中天敌幼虫生长发育和变态，而灭扫利和水胺硫磷常用剂量对两种天敌直接杀伤作用很强。

| Abstract: | The effect of the chitin synthesis inhibitor Dichlorbenzuron on the asiatic apple leaf miner(AAL)Lithocolletis ringoniella Mats, and its two major enemies was studied in the field and laboratory. 30 days of exposure, the effects of Dichlorbenzuron(125mg/L), fenpropnthrin (100mg/L ) and isocarbophos (400mg/L ) to control asiaticapple leaf miner are 99. 1 %, 41. 0% and 52.1 %;respectively. Dichlorbenzuron is saferto the adult, larvae and pupae of Eulophidae, Ageniaspisn testaceipes Ratz, and has nosignificant effect to the larvae of Lets axyridis (Pallas ). Fenpropnthrin and isocarbophosare very danger to the two natural enemies. |
